geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (or gas) migration in a human-made project, structure, or system.

Geomembranes are the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications.

GSE uses the highest quality resins to manufacture the widest selection of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) geomembrane products available in either a black, green or white upper surface, and in either a smooth or textured single or double-sided surface. All of GSE’s geomembranes are available with a conductive lower surface to allow for effective leak testing of installed geomembrane
